Benefits of technology

It is, therefore, an object of the invention to provide a mechanism control means that will prevent the mechanism from failing in the on position.
It is another object of the invention to provide a mechanism control which will limit the operation of the mechanism to a predetermined length of time or to a predetermined number of events.
It is another object of the invention to provide a mechanism control means which will control the length of a single operation of the mechanism, control the number of operations of the mechanism, and provide audio and / or video warnings and / or means to deactivate the mechanism when a malfunction occurs.
It is still another object of the invention to provide a microprocessor program to protect the user of the device from overexposure to ultraviolet radiation.

Problems solved by technology

In addition, failsafe circuitry monitors the sensor itself.
In kitchen equipment, e.g., ovens or deepfat fryers, a timer failure can result in a ruined product or a fire.

first embodiment

the subject inventive device is a safe source of ultraviolet phototherapy which protects the patient from inadvertent overdosage of prescribed treatments of ultraviolet radiation, UVA, PUVA, or UVB, by novel means for restricting the length and number of treatments; which permits the patient to receive UV treatments at home; and which provides the physician with means to prescribe home treatment while maintaining reasonable control over the treatments.

It will be appreciated that the ultraviolet ray-dispensing apparatus portion of the invention may take many forms. The apparatus may be a flat rectangular panel, waist high or full body length, which houses several fluorescent tubes. The tubes may be UVA, UVB, or a combination of both. The apparatus may comprise a full enclosure cabinet which completely surrounds the patient with fluorescent ultraviolet tubes. Another embodiment is a compact box-like device into which a hand or foot can be placed for treatment. Yet another embodiment i...

Abstract

A microprocessor to control and to prevent failure in mechanisms, particularly those that perform timed intervals of work. The microprocessor controls the length of each interval of work, and limits the mechanism to perform only a predetermined number of work intervals, after which it deactivates the device, allowing the mechanism to reactivate only after entry of a coded number or operation of a key switch. The microprocessor monitors all functions of the mechanism and includes a first failsafe circuit that shuts down the mechanism in the event of malfunction. A second failsafe circuit monitors the first failsafe circuit, and bypasses it to shut down the mechanism in the event of malfunction in the first failsafe circuit.

Description

1. Field of InventionThe general field of invention relates to failsafe controls for mechanisms that perform repetitive cycles of work. More specifically, the field of invention relates to failsafe controls for mechanisms used in the health care industry, including diagnostic and therapeutic mechanisms programmable to dispense selectable timed events. Most specifically, the field of invention relates to phototherapeutic radiation devices for home use.2. Description of Related ArtIn the general field of commerce there are many examples of automatic mechanisms that intermittently perform work responsive to actuating means, timed or non-timed. Furnaces, air conditioners, ovens, kitchen appliances, lights, photocopy machines, and telecommunication devices are but a few examples of miscellaneous prior art apparatus to illustrate the diversity of mechanisms that will benefit from the subject invention. In the health care industry, the device is of particular benefit to photochemotherapeut...
